Purpose? What's that?

Every human has a purpose, all you have to do is find it. This is what 21 year old Hunter has been told all of their life. They never quite understood other people, but still tried to find a purpose, since what are you without one? After a failed attempt at a career in one of the only things they loved, which was art, Hunter decides to just continue on with life as best they can, despite now being completely alone. But during a series of events that probably doesn't happen to most humans, Hunter realizes that they don't need any one specific purpose in life to enjoy it. They also find that they might not be as human as they were led to believe either.

Original story by me, I don't really know where I'm going with this but I had an idea at some point and decided to dump it on here.
